While Walk on Through is occasionally self-indulgent, it's more often endearing, funny and relatable, and makes you yearn for a cast recording. And it's not all about Creel: Ryan Vasquez and his powerhouse vocals are shown off in a series of small roles, including a wry Pollock and the brooding Russian author Vsevolod Garshin; in a stirring if incongruous number, Sasha Allen blows the roof off the joint as the triumphant subject of Lucas Cranach the Elder's Judith with the Head of Holofernes. Dramatic lighting by Jiyoun Chang and fabulous orchestrations by the band help elevate the show beyond cabaret.
